Conventive smoke filtering cleaner

Abstract

It is the object of the invention to present a construction for convective smoke filtering cleaners, especially for of the kind that mainly consists of a ceramic smoke filter, a drive fan, a smoke converting device, a water filter, a poison filtering device and a draw fan. Its major feature is that the ceramic smoke filter percolates the black smoke in the exhaust duct and turns it into white smoke, and then the drive fan makes white smoke quickly flow into the smoke converting device. The water supply system of the smoke converting device keeps water flowing around the wall of the exhaust duct and atomized water spraying incessantly in the duct. A rotating reservoir atomizes water and sprays over the inside wall of the duct. Consequently, when the white smoke arrives at the smoke converting device, atomized water drops can completely absorb and purify the smoke. The drifting dust and impurities in smoke along with water fluid are collected in the water filter installed under the smoke converting device. Because that a poison filtering device is built behind the water filter and a drive fan on the top of the poison filtering device consecutively operates, the gas passing through the smoke converting device is totally sucked into the poison filtering device.

I claim: 
     
       1. A construction of a convective smoke filtering cleaner, comprising mainly a first exhaust duct, a ceramic smoke filter, a second exhaust duct, a driving device, a drive fan, a smoke converting device, a water filter, a reservoir, a poison filtering device, and a draw fan, in which the front end of the first exhaust duct connects with a burner; wherein the ceramic smoke filter is built, so that the black smoke released from the burner can be percolated and turned into white smoke; characterized in that: the second exhaust duct is built perpendicular to the ground, wherein the upper end connects with the rear end of the first exhaust duct, a leakproof cushion and a cover plate are secured on the top and a locating plate placed on the bottom with a locating bearing at the center of the plate;   the driving device comprises of a drive motor and two drive shafts, the shfts keep synchronous motion with the shaft of the drive motor via belt pulleys and transmission belts, one of the drive shafts is in cross shape and is installed right at the center of the second exhaust duct, in which the upper end goes through the leakproof cushion and the cover plate with a stop block near the upper end, the lower end is held by the locating bearing of the locating plate, the other shaft is installed in the poison filtering device, the drive fan is mounted on one of the drive shafts of the driving device and is in the right position near the upper end of the second exhaust duct so that the white smoke in the first exhaust duct will be accelerated flowing into the second exhaust duct;   the smoke converting device is installed in the second exhaust duct and is right under the drive fan, comprising a water supply system and a reservoir; in which the water supply system is equipped with a water conduit with threads at the front end, through the porthole on the second exhaust duct wall, the water conduit is connected with a water supply pipe, at the ends of the water conduit neat the wall are semiconical water supply heads, the water supply head is a hollow compartment, capable of accommodating water fluid, with a slant surface made of a spring plate, the spring plate fixed at the upper end closes the water supply head tightly when the compartment is empty, as the compartment is filled with water, the spring plate will be lifted up and water fluid flows sectorially over the second exhaust duct wall, a water spray nozzle looking like a bath shower sprayer is in the position between two water supply head, which sprays atomized water downward and fills the whole space of the second exhaust duct, the reservoir is a cylindrical installation with a hole at the bottom, through the hole, the drive shaft of the driving device is fixed on the stop block, many water holes scatter over the cylinder wall, near the interior upper end is a water tray with many ventholes on its surface, the water tray has a hole at its center, which is used for accommodating the drive shaft, in addition, a water bowl is installed near the lower end of the cylinder, there are many holes of small diameters and a few partition plates on the surface of the water bowl other than a through-hole at the center for the drive shaft of the driving device, as the water spray nozzle in the water supply system sprays water fluid downwards, the reservoir stretches and fines water drops by its rotation;   the water filter having a container is installed at the bottom of the second exhaust duct, a water hole on the top of the container opposes to the bottom of the second exhaust duct, the bottom of the container is oblique backwards with a water slot at the rear end, the front and rear end surfaces are open and a door is installed at the front end; a filter core dwells in the container so that the dust and impurities in smoke can be separated out and water fluid filtered;   the water collection tank is installed under the bottom of the water filter to collect filtered water fluid, at the bottom of the tank is a water conduit, the water in the tank can be sent to the water supply system in the smoke converting device via a water pump;   a poison filtering device with a receptacle is installed behind the water filter, one side of the lower end of the receptacle has a hole opposing to the rear end of the container of the water filter, a leakproof cushion and a cover plate are secured on the top of the receptacle, a locating plate is built at a proper position near the upper end with a locating bearing at its center so that the other drive shaft of the driving device can go through the cover plate, the leakproof cushion with the other end held at the locating bearing, there is at least one poison filter in the receptacle, a cover plate at the bottom of the receptacle is used for supporting or approaching the filter;   a draw fan is mounted on the drive shaft of the, driving device and is in the interior of the receptacle, it may continuously draw off waste gas;   by means of the incorporation of the aforesaid mechanism motion, it constitutes an apparatus of a convective smoke filtering cleaner suitable for small exhausted gas release.
